AUTOMATIC STREET OR STATION INDICATOR.

SPECIFICATION forming part of Letters Patent No: 391,699, dated October 23, 1888.

Application filed January 30, 1888. Serial No. 262,387. (No model.)

.[b all whom it may concern.-

Be it known that I, SAMUEL M. FRIEDE, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Inn 5 provenlent in Automatic Street or Station Indicators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which- Figure I is a sectional end view ofa car with my indicator attached, showing the automatic action of the rocker-arm, under the influence of the riding buffer-pin attached to the post, by which the indicator is operated. Fig. II is an enlarged perspective view of the rocker arm, reactionary springs, and means of attachment to the car. Fig. III is an enlarged perspective view of the bufferpost and the riding buffer-pimwith the curvilinear inclined 2: track on which itrides. Fig. IVis an enlarged vertical sect-ion taken on line IV IV, Fig. V, showing the rolls that carry the indicatorscroll, the lamp that lights the scroll, also the alarnrbell. Fig. V is an enlarged horizontal 2 section taken on lineV V, Fig. IV, showing the indicator as seen from beneath, the trip lever, alarm-bell, and actnatingspring. Fig. VI is an enlarged top view, of the buifer-pin, the inclined track on which it rides, the rock- 0 er-arm that it operates, and the reactionary springs that bring back said arm to its normal position; and Fig. VII is an enlarged perspec tive View of the head of the buffer-post and the inclined curvilinear track on which the 5 riding bufferpin travels. Fig. VIII is a de tail of buffer-post with set screws to clips.

This invention relates to devices for automatically indicating to passengers of railwaycars the next street or station at which the 0 train stops; and the invention consists in features of novelty,hereinafter fully described, and pointed out in the claims.

Referring to the drawings, in which similar figures of reference indicate like parts in all 5 the views, 1 represents a car to which my indicator-rolls are attached.

2 is the indicator-chamber, which inclose's the spools 3and 4, the indicating-scroll 5, that carries on its face the names 6 of the street or station next ahead, thelamp 7, that illuminates :0 the scroll after night, the coil-spring 8, its attached gearing, and the aIarmbell. One end of the coilspring is secured to the pin 9, that is itself secured to the floor of the indicator-- chamber, and the other end is secured to the 5 5 shaft 10, which has bearings 11 in the top and bottom casing of the indicator-frame.

A drive gear-wheel, 12, on the shaft meshes into the sprocket or spur wheel 13, which is rigidly secured to the sleeve 14, that (0 carries the spool 3, and is itself carried and has a loose bearing on the shaft 15, one end of which is provided with a screw-thread, 16, that engages in acorresponding thread, 17, in the upper casing of the indicating-chamber. Athumb-knob, 18, at the lower end of said shaft provides the means forturning the same when it has been run through the sleeveand is made to engage in its screw-seat. The corresponding spool, 4, is seated on the sleeve 19, which surrounds the shaft 20, to which it is rigidly secured by the pin 21, so as to give the spool a forced rotation with the shaft when it has been placed in position and the pin inserted. The ends 22 of the sleeve form shoulders that keep the ends of the shafts in their bearings 23 in the upper and under casing of the indicator-chan1ber. The lower end of said shaft has a square seat, 24, for a common cranlchandle to fit thereon when the scroll is to be wound up.

25 represents the alarm-bell, which is suspended from a pendent rod, 26, that is secured to the tablet 27, which is fastened to the up per casing of theindicator-chamber. Aspringstem hammer, 28, is secured beneath the tablet outside the bell by a pivot-pin, 29, and a reactionary spiral spring, 30, is secured to the pivoted shaft of the hammer and at its other end to the tablet above the bell. A ing, 31, o on'the upper disk of the spool 4 (when the spool is revolving as it pays out the scroll) strikes the trigger-arm 32 of the handle of the hammer, turns it on its pivot, and the reactionary spring, in conjunction with the vibrat- 5 ing springsteni 33 of the hammer, causes its ball 34 to' rciteratedly strike the bell. A pin,

35, in the tablet limits the reactionary movement of the hammer, and so presents its continuous pressure against the bell under the in fluence of the spring. A lug, 31, is pivotally fastened to the upper disk of said spool by the pin 36, and has atrigger-arm, 31, against which a spring, 38, presses to force the face of the lug outward past the periphery of the disk, so as to strike the trigger of the hammer-handle as it passes. A pin, 39, against which the trigger-arm is projected by said spring, limits the outthrow of the catch lug 31. The said lug has a round back or outer edge, so as to enable it to ride under the trigger-arm of the bell-hammer without hinderance and to pass any other obstruction when the spool, with its scroll and the actuating coil-spring 8, is being wound up by the crank on the shaft 20.

The indicating-scroll 5 is secured at its ends to the spools 3 and 4, so that as the spool 4 is wound up it unwinds from spool 8, the gearing in connection with which winds up the coil-spring 8, and thus lays up the springpower that automatically operates the indicator-soroll.

A pendent door, 40, hinged at 41 to the door-cap 42 above it, has an elongated opening in its center, inwhich a pane of glass, 43, is preferably inserted to keep the dust from the chamber. The name of the street or station next ensuing is thus plainly exhibited to the passengers through said opening,whether glazed or otherwise. As a pointer and to explain the index, the words Next Station or Street (relatively according to whether it be a steam or street-railway car) are painted or otherwise placed on the left-hand of said Window in the door.

44 represents a dog-pawl that is secured by the pivot-pin 45 to the lower disk of the spool 4. A trigger-arm, 46, on said pawl is engaged by a spring, 47, that is secured to the disk and forces said trigger-arm against the stay-pin 48. Said trigger-arm by its reverse pivotal action projects the dog-lip of the pawl beyond the periphery of the disk, so that it engages with the catch-hook of the triplever 49, which is rigidly held between the forks of the trigger-arm 50, with which it is pivoted by the pin 51 to the angle-brackets 52, that are secured to one end of the casing of theindicatorchamber above and below the slotted aperture 53, through which said trigger lever works.

A reactionary spiral spring, 54, is secured to the trigger-arm of the trip-lever 49 and to a staple, 55, that projects from the end of the casing,and said spring reacts on the trip-lever after its trip and brings its catch-hook back into engagement with the dog-pawl to arrest the rotary movement of the spool after a single circuit. A dog-cleat, 55'}, on the lower disk of spool 4 arrests the rotation of the spool if for any cause the pawl 44 fails to catch the hook of the trip-lever 49.

The trigger-arm 50 is pivoted on the fork of the link 56 by the pin 57, and said link is pivoted to the crank-arm 58 by the pin 59. Said crank-arm is rigidly secured to the inner section, 60, of the compound rocker-arm.

The rockerarm is supported at its inner end by the socket'bracket 61, which is secured to the inner side of the cupola of the car-roof and by the vertical journal-bracket 62, that is secured on top of the lowersection of the arched roof of the car. An enlargement of the outer end of the inner section of the rocker-arm forms a joint head, 63, in the bifurcated end 64 of which the outer section, 65, of the rocker-arm is seated and connected by the pivot-pin 66.

A curved arm, 67, is seated in a slot, 68, in thejoint-head, in which it is rigidly secured. Twin spiral springs 69 are secured to the ends of the curved arm at one end and at the other to the perforated projecting lugs 70 a certain distance in advance from its pivoted connection on the outer section of the rocker-arm. This double reactionary spring attachment of the pivoted outer section of the rocker-arm allows it free lateral swing and return movement, as will be more particularly shown in the operative description.

The outer section of the rocker-arm telescopes into an angletube, 71, within the vertical section of which is also telescoped a pendent rod, 72. A set-screw, 73, and a similar screw, 74, relatively set the horizontal and vertical length adjustment of the rocker-shaft.

represents the buffer-post, which is set alongside the track at a sufficient distance therefrom not to unduly interfere with the passing trains, but sufficiently near for its riding buffer-pin to trip the rocker-shaft. Near the head of the post it is encircled by a collarclip, 76, within the socket-lug 77 of which the foot of the buffer-pin is seated, and a similar collar-clip, 78, still nearer the head of the post, seats the upper end of the vertical section of said buffer-pin in the socket of its projecting lug 79, and both clips are relatively set on the post when adjusted to the right height by the set-screws 80 and 81. A flanged collarclip,82,surmounts the last-named clip around the head of the post and is tightly secured thereto, when adjusted, by the setscrew 83, and carries riveted to its flanged side an inclined curvilinear trackway for use to be further disclosed in the description that now follows of the traveling buffer-pin.

84 represents the buffer-pin, which consists of a vertical rod,85,that is seated in the sockets of the lugs 77 and 79 of the clips 76 and 78,and is surmounted by the elbow 86,which connects it to the horizontal sleeve 87,that telescopes the adjustable contact-pin 88, that is set to its adjustment within the sleeve 87 by the screw 89, so as to be accommodated to the width of cars traversing the track. 90 is a key-pin at the foot of the buffer-pin to keep it from lifting out of its seat.

91 represents a journal-box truck, in which the telescopic sleeve 87 of the buffer-pin is seated and by it carried over the curvilinear inclines 92 of the reactionary track, whose rear bar,93, is secured by bolts 94 to the flanged IOC erated on.

wings 95 of the clip 82, that embraces thehead of the post, The said truck-boxing 91, that carries the buffer pin, is provided with perforated pendent lugs 96, in the perforations of which is secured the axle 97, that carries the track-wheel 98, which traverses the curvilinear inclines 92, and so the track.carries round the buffer-pin, when it contacts with the pondent-pin 72 on the rocker-bar of the car, and after performing its fu nctions,wl1en the bufferpin is released from the rockerbar, the truck carries back the pin down the incline to its normal position.

The indicating devices, with their actuating rocker-arms, 8m, are preferably duplicated, so as to be located at each end of the car, as each end alternately becomes the forward end, and in consequence the end toward which the seats of the passengers are faced. Bufferposts are also correspondingly located in po sitions required to operate the rocker-oars when the train is running either way.

The operation of my invention is as follows: The buffer posts are placed alongside the track, (preferably on the right-hand side rela tively to that on which the train is moving,to

which the buffer-pin operates, although they may be placed on either or both sides.) The posts are preferably planted at points adj oining the street or station the train hasjust left, so as at that point to change the indication from that of said street or station to that of the one next ensuing. Along single tracks the posts are placed on both sides of said track, so as to operate on the indicator of trains COllling from either direction. The post carries the compound riding buffer-pin 84, which is pivotally seated in the perforated lugs of ad j ustable clips that are seated on said post, and are held by set-screws at an adj nstable elevation suited to the height of the cars to be op- It will thus be seen that if there should be a change in the build of the rollingstock the elevation of the buffer-pin on the post can be raised or lowered in accordance with it and there secured by the set-screws. The buffer pin, besides being pivoted in the lugs of said clips in which it has both free rotary and vertical movements within certain limits, also rides on the truck-bearer 91, whose wheel 98 traverses the curvilinear inclines 92 of the bracket-track, which is secured to the head of the post. It will be seen that the peculiar conformation of said track allows the buffer pin to ride round when it strikes the rocker arm, and so in conjunction with the rocking of said arm after having tripped theindicator it disengages therefrom, and as it has run up the incline, it now, when liberated, runs down the same and returns to its normal position, ready for reaction when the next train passes. The finger 88 is adjusted in the sleeve 87 and there secured by its set-screw, so as to accord with the pendent rod 72 of the rock-bar that it actuates. The said pendent rod is adjusted to its right length in the sleeve 71 and secured there by its set-screw.

It will be seen that when the buffer-pin strikes the rocker-arm and is operating its trip on the indicator devices the forearm of the said rocker-arm turns on its pivot 66 with a sufficient lateral movement, in conjunction with the other devices already noted, to allow it free escape from the bu ffer-pin. The reactionary springs 69 then return it to its normal position ready for future action. The setscrew 73 is used to set the adjustment of the length of the forearm. When the rocker arm is thus operated by the bnfier-pin, its crank-arm 58, thronghits pivot-link, operates the trigger-arm and its trip-lever to trip the dog-pawl44t, that then allows a single rotation of the spool 4 under the influence of the coilspring, as hereinafter described.

The coil-spring 8, as described, through its shaft 10 and geared connections with the shaft 15 of the spool 3,0auses a rotary strain on said spool when wound up, and through the indicator-scroll, whose ends are secured to said spool and to spool 4 and wound around them, thereis provided a rotary strain also on thelatter spool. It thus follows, as stated, that when the dog-pawl 44 is tripped, as described, the spools make a single rotation, when the pawl is again engaged by thetrip-lever49,andas thecircumference of thelay on the spool,either when full or at the last lay of its uncoil,is sufficient for the length of scroll on which is recorded the name of the incoming street or station such name, when projected against the window of the indicator-chamber by the rollers 99 and 100, around which the scroll passes, is plainly exhibited to the passeugersin the car. A lamp back of the scroll illuminates the legend after dark.

A pivoted projecting lug, 31, on the upper disk of spool 4, (when the spool rotates,) as it passes, trips the hammer of the alarzmbell 25, the vibratory spring-stem of said hammer enforcing for a short period a reiterating striking of the bell,which calls the attention of the passengers to the change of name of the street or station presented by the indicator.

It will be seen that like slotted apertures, 53, to those shown on the right-hand side of the car are also shown on the left hand for the passage ofthe inner end of thorocker-arm, &c., when the actuating devices are required to be operated from the other side of the car. Then the buffer-posts, rocker arms, and other actuating devices will be located, or also located, on the reverse side to that before stated. A single indicator at one end of the car may thus, if desired, be made to answer the required purpose, (by transpositiom) when the train is running in either direction.

When it is desired to reverse the position of the actuating devices of the indicator or remove the scroll and spools for repairs or any other purpose, said parts can be easily taken out, after unscrewing the shaft 15 of the spool 3, (making use of knob 18 for that purpose,) withdrawing said shaft, and the removal of pin 21 and shaft 20 from within the sleeve of ICC spool 4, and then the spools and scroll can be removed without difficulty.

Ihe words Next Street or Station, asthe case may be, which are shown on the door on the left hand of the indicator-window to call the passengers attention to said indication, may be also placed on the other end of said window, so as to call attention thereto from the passengers on the other side of the car.

When the spring-coil is run out by the time the train has reached the end of the track, it is wound up again and theindicator-scroll reverse lapped around the spool 4 by the action of a handcrank of usual construction, which is fitted on the square stem 24 of the shaft 20, and when the one recording-indicator alone is used and it is desired to reverse it and its actuating devices at the end of the run it is easily accomplished after the withdrawal of the spoolshafts by the means described above.

101 is a small door within the door40,which opens the way for the deposit of the hand crank or other small tools when not in use.
